circRNA-disease information
Expression pattern:
UP
Associated gene: PSMC2
Associated microRNA: miR-1299
Biological function: Promotes CRC cell proliferation, colony formation, migration, EMT, tumor growth and lung metastasis, and inhibits apoptosis.
Molecular mechanism: ceRNA mechanism: Hsa_circ_0007718 acts as a sponge of miR-1299, reducing miR-1299-mediated inhibition of PSMC2 and promoting PSMC2 expression.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (promotes); migration (promotes); EMT (promotes); apoptosis (inhibits); metastasis (promotes); invasion (promotes)

Detected method:
Q
M
Validation methods:

Sanger Sequencing; RNase R Treatment; RT-qPCR; FISH / smFISH; Nuclear-Cytoplasmic Fractionation; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; In Vivo Animal Model; H&E Staining; Microarray

Clinical significance:

circ_0007718 might be a valuable candidate target for CRC therapy.

Description:

Hsa_circ_0007718/circ_0007718 is up-regulated in colorectal cancer tissues and cell lines. It promotes CRC progression by sponging miR-1299 and increasing PSMC2 expression, thereby enhancing proliferation, migration, EMT, tumor growth and lung metastasis while suppressing apoptosis. The study suggests circ_0007718 may be a potential therapeutic target for CRC.

Confidence score:

0.7938
